D-R 320 Dust Monitor for smallest to medium concentrations

The D-R 320 is based on the back-scattered light principle and is ideally suited for monitoring smallest to medium dust concentrations. The light scattered backward by these particles is detected and evaluated.

A unique feature of the D-R 320 is the automatic background light compensation with means of a patented optical system with dual detector. This allows for an easy and quick Installation without any adjustment. A light trap is not required.
